Once you've watched the Back To The Future movies a few times, you start noticing all the cool little details hidden in them -- like how Marty's reckless driving renamed a mall, or how Doc Brown's son probably peed himself in the last scene. Apparently, the filmmakers knew nerds would still be obsessing over their work 30 years in the future, so they made sure to pack the trilogy with as many cinematic Easter eggs as possible. It's almost like they had some sort of time ma- whoa.
Not all those hidden plot points are so innocent, though. The more you rewatch Back To The Future, the more you become aware of the dark truths lurking under its fun-filled surface, such as ...
Doc Likely Burned His Own House Down For The Insurance Money
Right after the fact that his best friend is a 17-year-old boy, the weirdest mystery surrounding Doc Brown is: What the hell happened to his sweet house? In 1955 he's living in a palatial mansion, but by 1985 he's shacked up in a garage in a Burger King parking lot, like a common Burger King assistant manager.
Doc's 1985 digs suck so much he's forced to live out "The Humpty Dance"
every time he has a woman over.
Thanks to Doc's serial-killer-like penchant for decorating his room with old newspaper clippings, the audience is informed that his house burned down -- but it's never explained how that happened. All we know is that after the fire Doc sold his property to developers, presumably working for Burger Duke.
Ah, yes, remember when you went through that devastating tragedy and then
framed the newspaper articles about it?
Here's where things start to get suspicious: The news article also describes Doc as a "bankrupt inventor," which is weird, because earlier in the movie he told Marty that he'd spent his entire family fortune building the time machine. The paper is dated 1962 -- so Doc must have used up all of his money in just seven years, leaving him bankrupt and desperate. Since Shark Tank didn't exist in 1955, torching the Brown mansion may have been the only way Doc could think to raise the funds for his time machine.
In doing so, Doc would get the insurance money as well as the money from the sale of the property. And he needed both, because even after getting all of that money, by 1985 his bachelor pad/filthy garage is full of "past due" bills. It doesn't help that a big part of his budget goes to buying dozens of clocks for no apparent reason.
